The Samsung Galaxy S6 Edge+ on AT&T is currently getting a new security update. The update started seeding earlier this week, and installs the February Android security patch.
If you’ve got a Galaxy S6 Edge+, then you should install this security update as soon as possible. The build number is G928AUCS4CQB2 and the update is available as OTA. There’s nothing new in this build except for the security patch.
This update is still based on Android 6.0.1 Marshmallow, but not to worry, the device will be updated to Nougat soon. Recently, Samsung released the Nougat update for the Galaxy S6 Edge + in Turkey.
As usual, it is recommended that the device has more than 50 percent charge before installing the update. And, it is also better to be connected to a stable Wi-Fi network. If you haven’t received the update yet, you can manually check for it from Settings > About device > System updates.
